Shut down against hibernate set up

All right, I´m sure I´m gonna get the good ol´¨do a search¨ think... I did and the results I got are confusing. When we´re talking about the M2 atx SHUTTING DOWN the PC some people mean ¨actually shutting it down¨ others ¨hibernate¨... so...

I want my M2 to resume from Hibernation when I turn the ignition on and go into hibernation when I turn the ignition off. I assume that exclude any HARDOFF otherwise it wouldn´t be able to come back from hibernation since the PC would have to boot.

I guess mode 5 would do , is it a big problem for battery draining. (I always used hibernation with my laptop and neber had any problem).

UMMM yup if you had searched you would have seen that hibernate doesn't use any power at all. You can completely remove power and it will come back as per normal because the state is righten to disk. Its standby that needs power as the state is kept in ram.

You need to go to power management, advanced tab and set when I press the power button to hibernate.
